Appendix. Example of precise targeting of a marker with elementary HIFU sonication: T1-w VIBE (a) and in situ magnitude GRE-EPI thermometry (b) images showing the marker and the trajectory of the RF needle; temperature elevation (c) during HIFU sonication on a marker (blue plot) and in bulk tissue away from the marker (black plot) and a camera picture (d) of the elementary HIFU lesion centered on the ballistic marker.
